Fixed issues where some third-party controllers wouldn't sync. Network Stability: Improved local wireless and eShop stability. Homebrew Fixes:
While the main CPU firmware updates, your NVMe drive or GPU may still have its old firmware expecting specific handshake timings. This can manifest as PCIe Correctable Errors in the system log. A physical reboot resynchronizes all buses; a rebootless update does not. Firmware 19.0.1 -Rebootless Update-.zip
This tool will verify if your specific hardware revision (e.g., Rev 2.1 PCB) supports rebootless patching. Note: Some OEMs lock this feature behind a BIOS flag ("Live Patch Enable"). This can manifest as PCIe Correctable Errors in
